basement; or near a swimming
pool; and the like.
8. Accessories. Do not place
this product on an unstable
cart, stand, tripod, bracket, or
table. The product may fall,
causing serious injury to a
child or adult, and serious
damage to the product. Use
only with a cart, stand, tripod,
bracket, or table recommended
by the manufacturer, or sold
with the product. Any mount-
ing of the product should fol-
low the manufacturer’s instruc-
tions, and should use a
mounting accessory recom-
mended by the manufacturer.
9. A Product and Cart
Combination Should Be
Moved with Care.
Quick stops,
excessive force, and uneven
surfaces may cause the prod-
uct and cart combination to
overturn.
10. Ventilation. Slots and
openings in the cabinet are
provided for ventilation and to
ensure reliable operation of
the product and to protect it
from overheating, and these
openings must not be blocked
or covered. The openings
should never be blocked by
placing the product on a bed,
sofa, rug, or other similar sur-
face. This product should not
be placed in a built-in instal-
lation such as a bookcase or
rack unless proper ventilation
is provided or the manufactur-
er’s instructions have been
adhered to.
11. Power Sources. This prod-
uct should be operated only
from the type of power source
indicated on the marking
label. If you are not sure
of the type of power supply
to your home, consult your
product dealer or local power
company. For products intended
to operate from battery power,
or other sources, refer to the
operating instructions.
12. Grounding or
Polarization.
This product may
be equipped with a polarized
alternating-current line plug
(a plug having one blade
wider than the other). This
plug will fit into the power
outlet only one way. This is a
safety feature. If you are
unable to insert the plug fully
into the outlet, try reversing
the plug. If the plug should
still fail to fit, contact your
electrician to replace your
obsolete outlet. Do not defeat
the safety purpose of the
polarized plug.
13. Power-Cord Protection.
Power-supply cords should be
routed so that they are not
likely to be walked on or
pinched by items placed upon
or against them, paying par-
ticular attention to cords at
plugs, convenience recepta-
cles, and the point where they
exit from the product.
14. Nonuse Periods. The
power cord of the product
should be unplugged from the
outlet when left unused for
long periods of time.
15. Outdoor Antenna
Grounding.
If an outside
antenna or cable system is
connected to the product, be
sure the antenna or cable sys-
tem is grounded so as to pro-
vide some protection against
voltage surges and built-up
static charges. Article 810 of
the National Electrical Code,
ANSI/NFPA 70, provides infor-
mation with regard to proper
grounding of the mast and
supporting structure, ground-
ing of the lead-in wire to an
antenna discharge unit, size of
grounding conductors, location
of antenna-discharge unit,
connection to grounding elec-
trodes, and requirements for
the grounding electrode. See
Figure 1.
16. Lightning. For added pro-
tection for this product during
a lightning storm, or when
it is left unattended and
unused for long periods of
time, unplug it from the wall
outlet and disconnect the
antenna or cable system. This
will prevent damage to the
product due to lightning and
power-line surges.
17. Power Lines. An outside
antenna system should not be
located in the vicinity of
overhead power lines or other
electric light or power circuits,
or where it can fall into such
power lines or circuits. When
installing an outside antenna
system, extreme care should
be taken to keep from touching
such power lines or circuits, as
contact with them might be
fatal.
18. Overloading. Do not over-
load wall outlets, extension
cords, or integral convenience
receptacles, as this can result
in a risk of fire or electric
shock.
19. Object and Liquid Entry.
Never push objects of any kind
into this product through
openings, as they may touch
dangerous voltage points or
short-out parts that could
result in a fire or electric
shock. Never spill liquid of
any kind on the product.
20. Servicing. Do not attempt
to service this product your-
self, as opening or removing
covers may expose you to
dangerous voltage or other
hazards. Refer all servicing to
qualified service personnel.
21. Damage Requiring
Service.
Unplug this product
from the wall outlet and refer
servicing to qualified service
personnel under the following
conditions:
a. The power-supply cord or
the plug has been damaged; or
b. Objects have fallen onto, or
liquid has been spilled into,
the product; or
c. The product has been
exposed to rain or water; or
d. The product does not oper-
ate normally when following
the operating instructions.
Adjust only those controls that
are covered by the operating
instructions, as an improper
adjustment of other controls
may result in damage and will
often require extensive work
by a qualified technician to
restore the product to its
normal operation; or
e. The product has been
dropped or damaged in any
way; or
f. The product exhibits a dis-
tinct change in performance –
this indicates a need for
service.
22. Replacement Parts. When
replacement parts are required,
be sure the service technician
has used replacement parts
specified by the manufacturer
or that have the same charac-
teristics as the original part.
Unauthorized substitutions
may result in fire, electric
shock or other hazards.
23. Safety Check. Upon
completion of any service or
repairs to this product, ask the
service technician to perform
safety checks to determine
that the product is in proper
operating condition.
24. Wall or Ceiling Mounting.
The product should be
mounted to a wall or ceiling
only as recommended by the
manufacturer.
25. Heat. The product should
be situated away from heat
sources such as radiators, heat
registers, stoves, or other
products (including amplifiers)
that produce heat.
